The CDC has just announced that you should not wear these masks
Disease and prevention control centers simply revised their face protection advice.
We are all bombarded by online ads for facial masks everywhere these days. Wearing one is the responsible thing to do, but what do you choose? Disease and prevention control centers simply stated that a type must certainly be turned off the table (and out of your face): all masks with valves or vents.
Thursday, the CDC officially advised that people should not wear facial masks that have upsets or valves, depending on the section of the masks of his website.
They allow viruses to escape
Face masks with upheavals or valves may be more comfortable for users because they allow air to escape the mask; who keeps the cooler users. Unfortunately, this can also allow viruses such as coronavirus to escape.
In May, health officials had warned that this type of mask could benefit the bearer but is little to take advantage of public health. "The valves actually make things much more comfortable because they make the mask much more breathable," said Dr. Ali Raj, Executive Vice President of the Massachusetts General Hospital Medicine Department, "said Boston Globe. "But they do not do anything in terms of filtering just that the bearer exhales."

One of the most important challenges of coronavirus is that many people infected up to 40% -May and do not have any symptoms, allowing them to broadcast it widely. This has proved to be a major challenge for states and localities that have established locking and reopening plans.
From the beginning of the pandemic, the mask requirements vary from state to state, which caused confusion in some states emerging from an original lock.
"When you have people coming out and companies open a backup, you could as well as people do not wear masks if they have a one-way valve," Raj said, "because they breathe just in the air without filtration. "
But with regard to the CDC, the valve masks are bare. The officials say that an N95 respirator with an expiration valve "provides the same level of protection to the wearer as the one that does not have a valve." However, says the CDC, "respirators with expiration valves should not be used in situations in which a sterile field must be maintained ... because the expiration valve makes it possible to escape into the sterile field" .
